DUST-GUARD FOR JOURNAL-BOXES.

Specification of Letters Patent.

Application filed August 29, 1917. Serial No. 188,698.

To all whom it may concern:

Be it known that I, HARRY C. McCAR'rY, a citizen of the United States,residing in VVilliamsport, in the county of Lycoming and State ofPennsylvania, have invented certain new and useful Improvements inDust-Guards for Journal-Boxes, of which the following is aSpecification.

This invention relates to journal-boxes, and especially to journal-boxesused upon railroads, street railway or mine or like cars, in which thewheels are fixed to the axles; and axles revoluble in journaLboxes. The:present invention comprises a new and im proved form of dust-guard forencircling. the axle for preventing the entrance of dust or dirt, at thesame time assisting, by capillary-attraction, the feeding of oil orother lubricant to the journal. is

This invention is a modification of, and an improvement on the devicesshown, de scribed; and" claimed in my two Letters Patent for adust-guard, No, 711,641, granted October 21, 1902; and Letters, PatentNo. 743,653, for a journal-box, granted I November 10,1903; and myapplication,

Serial No. 150,917, filed February 26, 1917, I; have found, byexperience that a very eiiicient and durable dustguard and a veryefficient means of lubricat on is formedlby having such guard stiffenedat its outer edges by means of folded pieces of fabric; and that itsinsertion and removal are facilitated by such stiflening, and I havealso found that such a dust-guard is easily placed in position in thepocket provided in the journal-box for receiving such dust-guard; andthat the guard is snugly received in said pocket. L y 1 i My saidinvention may be very cheaply constructed and is fully shown, describedand claimed in the following specification, of which the accompanyingdrawing forms a part; wherein similar letters and numerals of referencedesignate like or equivalent parts throughout the several views and inwhich y a Figure l is aview in longitudinal central vertical section ofmy improved journalbox and dust-guard, with the oar-axle and dust-guardin position; I

Fig. 2 is a view of such dust-guard and axle in vertical section, takenon the line 2-2 of Fig. 1, looking toward the right in the direction ofthe; arrow; I i

Fig :3 is a v w in deta l inipe sp st v and also central verticalsection on the line as of Fig. 2; r I

Fig. 4; is a view in detail of a portion of the axle, with thecontacting portion of the dust-guard shown in section mounted thereon.Referring more particularly to the drawmg: i

A designates a car journal-box which may be that shown, or may be theMaster Car Builders journal-box having the front open-v ing, forintroducing lubricating-material, closed in the well-known manner by journa1- box lid B, pivoted at 10, and provided with the spring 11, formaintaining the same in the open position for cleaning, or introducingnew lubricant. Such journal-box is, of course, provided with suitablemeans for securing the same rigidly to the truck-frame; but as thisforms no part of my invention, I have not deemed it essential to show orindicate this part of the construction. i

a At the inner end of such journal-box, is formed the pocket 12' openatthe top, having the inner-Wall 13, and the outer-wall 14;

and the side-walls 15 and bottom 16; which pocket is usually of therectangular form clearlyindicated in Fig. 1. g

posed in the well-known manner, the usual bearing-plate D. 7

My improved dust-guard, used with this particular form of j ournal-box,comprises a rectangular dust-guard body G, usually and preferably formedof two superposed sheets of suitable flexible woven wick-like material,such as cotton-duck, etc., which will capil larily feed the lubricatingoil from the bot tom of the journal-box, to the center of said guard G,and to the axle. As shown in the drawing, such dustguard G, is formed ofthree or more plies of canvas or other suitable wick-like material,having the central opening 1?, prevented from spreading adjacent to suchopening by the circular line of stitches 18, surrounding such opening;and secured to one face of the sidesv and bottom and top of such one ormore ply flexible fabric dust guard, is an outer rectangular Lstifleningframe '19 composed of suitable wick-like fabric, for instance, the samefabric as the itself, as atgo, whereby the frame comprises four plies asshown inFigs. l, 3, and i. The plies of the frame are stitched togetherby the lines of stitches and then the Whole is stitched to the body ofthe dustguard by lines of stitches 26 passing entirely through the oneor more plies of the dustguard body and two or more plies of the f ame.

The main body portion of the dust-guard G is strengthened by theinsertion, between the plies thereof, of a strengthening ply extendingto the outer edge of the dustguard and terminating at its inner edgenear the line of stitches 1S.

When the guard is in position the frame forms a somewhat yieldingcombined packing and stiffening which prevents entrance of dust throughthe open top of the pocket.

In assembling, the dustguard placed in position in the dust-guard pocket12, by slipping the same in from the top. When in such position thecentral orifice 1'? of the dust-guard G, being slightly smaller indiameter than the inserted axle C, the one or more plies thereof, Willbe slightly spread apart at the bottom as clearly indicated at 26 of F land at; whereby the ingress of dust and dirt is prevented and thefeeding of the oil contained in the bottom 2'7, of the journal-box Awill be more liberally distributed to the axle.

It is evident that many changes and modifications in the construction,combination and arrangement of the several parts of my device hereinshown, described and claimed, may be made, Without departing from thescope of my invention, but I do not intend to limit myself to the exactconstruction shown and described.
